Abstract [en]

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.

Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results. The construction moisture characteristics of the two materials were compared in a simulation program called WUFI 5.1 PRO. Literature were done to understand moisture and understand how to use the simulation program.

This study provided results about how well suited the materials were for Fiskarhedenvillan AB:s passive house. The main conclusions were that both of the materials are functioning from a moisture standpoint, although the Rockwool with vapor barrier provided better values than the polyurethane insulation. These conclusions applied to both roof and wall constructions. From a fire standpoint both of the materials worked in the wall construction. The roof should however retain the current construction design. The solution with polyurethane insulation does not meet the fire requirements.
